8 3.2 CONFIGURATION STRAPS In addition to the configuration switches described above, the Model 1075 is also equipped with two internal straps that set the DTE/DCE Configuration and the DB-15 Shield. In order to configure these straps, you must open the Model 1075 case. NOTE: Before opening the case, determine whether the default settings are correct for your application (see Sections and 3.2.4) Opening the Case To open the Model 1075 insert a flat head screw driver into an open slot on either side of the case, as in Figure 3. Twist the screw driver head slightly and the top half of the case will separate from the lower half, as in Figure 4, below. Figure 3. Opening the 1075 Case with a Small Screwdriver Figure 4. Opening the 1075 Case With a Small Screwdriver To close the case, fit the 2 halves together snugly and snap them back in place. 7

9 DCEDTE DCEDTE Location of the Internal Straps Figure 5 (below) shows the location of the DCE/DTE switch and the JP1 strap on top side of the the PC board. JP1 Strap Front DTE/DCE Strap Rear Figure 5. Position of DTE/DCE and JP1 Jumper Straps on Model 1075 PC Board Setting the DCE/DTE Strap The X.21 interface on the Model 1075 is DCE/DTE switchable. The default setting is DCE, based upon how the Model 1075 sees its own orientation. When configured this way, the Model 1075 will want to connect to an X.21 DTE device. Re-positioning the DCE/DTE strap will enable the Model 1075 to connect to an X.21 DCE device (See Figure 6, below). Figure 6. Close-Up of Model 1075 PC Board With Close-up of DCE/DTE Strap Default Setting = DCE The X.21 DCE/DTE strap is located near the DB-15 connector on the PC board. The arrows on the top of the strap indicate the configuration of the Model For example, if the DCE arrows are pointing toward the DB-15 Connector, the Model 1075 is configured as a DCE and must connect to an X.21 DTE device. To change the DCE/DTE orientation of the Model 1075 X.21 interface, simply remove the strap and rotate it 180 o so the appropriate arrows are pointing toward the DB-15 Connector. 8

10 3.2.4 Setting the JP1 Shield Strap The setting of JP1 determines whether the shield (pin 1) of the X.21 interface is connected signal ground. In the default setting, DB-15 shield is connected to signal ground. The X.21 shield is not connected to signal ground when the jumper is placed on pins 1 and 2. See Figure 7, below Front Rear Figure 7.

11 4.0 INSTALLATION When you have properly configured the configuration switches and straps, you are ready to connect the Model 1075 to connect to your system. This section tells you how to properly connect the Model 1075 to the twisted pair. 4.1 CONNECTION TO THE TWISTED PAIR INTERFACE The Model 1075 supports full or half duplex communication between two X.21 devices at distances to 6 miles (9.7 km) and data rates to 64 kbps. There are two essential requirements for installing the Model 1075: 1. These units work in pairs. Therefore, you must have one Model 1075 (or compatible unit) at each end of a two twisted pair interface. 2. To function properly, the Model 1075 needs two twisted pairs of metallic wire. These pairs must be unconditioned, dry metallic wire, between 19 and 26 AWG (the higher number gauges may limit distance somewhat). Standard dial-up telephone circuits, or leased circuits that run through signal equalization equipment, are not acceptable. For your convenience, the Model 1075 is available with two different twisted pair interface options: RJ-11 jack or RJ-45 jack Twisted Pair Connection Using RJ-11 OR RJ-45 The RJ-11 and RJ-45 connectors on the Model 1075's twisted pair interface are pre-wired for a standard TELCO wiring environment. The signal/pin relationships are shown below. RJ-11 SIGNAL RJ-45 SIGNAL 1...GND 2...RCV 3...XMT 4...XMT 5...RCV 6...GND 1...N/C 2...GND 3...RCV 4...XMT 5...XMT 6...RCV 7...GND 8...N/C 10

12 When connecting two Model 1075s, it is necessary to use a "crossover" cable. The diagram below shows how a cross-over cable should be constructed for an environment where both Model 1075s use a 8- wire RJ-45 connector. Similar logic should be followed when using RJ- 11 connectors or a combination of the two. RJ-45 Cable (8-Wire) SIGNAL PIN# PIN# SIGNAL N/C 1 1 N/C GND GND RCV XMT XMT RCV XMT RCV RCV XMT GND GND N/C 8 8 N/C Connection to ground is optional Figure 8. Pin Number Assignments for RJ11 and RJ45 Modular Jacks 4.2 CONNECTION TO X.21 INTERFACE To connect the Model 1075 to a piece of data terminal or data communications hardware, use a straight through DB-15 cable. Plug the cable directly into the DB-25 port on the rear of the Model If it is necessary to construct a special interface cable, please refer to the pinout diagrams in Appendix C. Notice! Any terminal cable connected to the Model 1075 must be shielded cable, and the outer shield must be 360 degree bonded at both ends to a metal or metalized backshell. 11

13 4.3 AC POWER CONNECTIONS Power is supplied to the Model 1075 by a 9 VDC, 1 A wall mount transformer. This transformer connects to the Model 1075 by means of a cannon jack on the rear panel. The Model 1075 is powered-up as soon as it is plugged into an AC outlet there is no power switch. 120 VAC Power (US) The 120 VAC adapter supplied with the standard version of the Model 1075 is a wall mount type, and may be plugged into any approved 120 VAC wall plug. 230 VAC Power (IEC) The 230 VAC adapter supplied with the international version of the Model 1075 is equipped with an IEC-320 shrouded male connector. This connects with one of several available country-specific power cords (see the ordering information in Appendix C.) You may purchase these power cords from Patton Electronics at: (301) ; or, support@patton.com; or from a local vendor. 12

14 5.0 OPERATION Once the Model 1075 is properly configured and installed, it should operate transparently as if it were a standard cable connection. Section 5.0 describes the LED status monitors and the built-in V.52 and V.54 test modes. The Model 1075 is powered by a 9V DC external wall mount transformer. To power up the unit, connect the power supply cord to the power jack on the rear of the Model 1075 and plug the power adapter into the wall. There is no ON/OFF switch. 5.1 LED STATUS MONITORS The Model 1075 features six front panel LEDs that indicate the status of the unit and the communication link. Figure 9 shows the front panel location of each LED. Following Figure 9 is a description of each LEDs function.

Red indicates that Control from the DTE is inactive. Glows green to indicate that the Indication from DCE is active. Red indicates that the Indication from the DCE is inactive. Glows red when errors are detected during the 511 or 511/E BER tests. Glows red when the V.54 loopback test or V.52 BER tests are initiated. 13

15 5.2 TEST MODES The Model 1075 offers two V.54 test modes to evaluate the condition of the modems and the communication link. These tests are activated from the front panel Local Analog Loopback (LAL) The Local Analog Loopback (LAL) test checks the operation of the local Model 1075, and is performed separately on each unit. Any data sent to the local Model 1075 in this test mode will be echoed (returned) back to the user device. For example, characters typed on the keyboard of a terminal will appear on the terminal screen. To perform a LAL test, follow these steps. A. Activate LAL. This may by moving the front panel toggle switch DOWN to LAL. Once LAL is activated, the Model 1075 transmitter output is connected to its own receiver. The test LED should be lit. B. Verify that the data terminal equipment is operating properly and can be used for a test. If a fault is indicated, call a technician or replace the unit. C. Perform a Bit Error Rate (BER) test on each unit. If the BER test equipment indicates no faults, but the data terminal indicates a fault, follow the manufacturer s checkout procedures for the data terminal. Also, check the interface cable between the terminal and the Model Remote Digital Loopback (RDL) The RDL test checks the performance of both the local and remote Model 1075, and the communication link between them. Any characters sent to the remote Model 1075 in this test mode will be returned back to the originating device. For example, characters typed on the keyboard of the local terminal will appear on the local terminal screen after having been passed to the remote Model 1075 and looped back. To perform an RDL test, follow these steps: A. Activate RDL by moving the front panel toggle switch UP to RDL. B. Perform a BER test on the system. (cont) 14

16 C. If the BER test equipment indicates a fault, and the Local Analog Loopback test was successful for both Model 1075s, you may have a problem with the twisted pair line between the modems. You should then check the twisted pair line for proper connections and continuity How to Use the V.52 BER Test Independently The V.52 BER test can be used independently of the V.54 loopback tests. This requires two operators: one to initiate and monitor the test at the local Model 1075, and one at the remote Model To use the V.52 BER test by itself, both operators should simultaneously follow these steps: 1. Locate the 511/511E toggle switch on the front panel of the 1075 and move it UP. This activates the V.52 BER test mode and transmits a 511 test pattern to the other unit. If any errors are present, the receiving modem s red Error LED will blink sporadically. For this test to work, make sure the 511 switch on both Model 1075s is on. 2. If the test indicates no errors are present, move the V.52 toggle switch DOWN, activating the 511/E test with errors present. If the test is working properly, the receiving modem's red Error LED will blink regularly. A successful 511/E test will confirm that the link is in place, and that the Model 1075 s built in 511 generator and detector are working properly. 5.3 POWER-DOWN There is no power switch on the Model You turn it off by unplugging the AC power adapter from the wall. 15
